Principe and application of cationic UV-Curing 

Cationic UV-Curing Principle

UV (Ultraviolet) curing material is formed under ultraviolet light, where a chemically active liquid formulation can be rapidly changed into a solid coating film on substrate surface. This innovative UV-curing technology has the characteristics of "5E": Efficiency, because UV curing equipment is compactly structured and it can realize continuous production for increased efficiency; Economy, because UV curing process can save raw materials and it can effectively reduce costs; Energy, because short curing time and no heating can save energy; Ecology, due to low VOC content and no excessive harmful gas in production; Enabling, because it is suitable for processing on surface of many kinds of substrate such as wood, metal, plastic, etc.

UV Coating / Ink Application

Epoxy resins are most widely used in coatings of different characteristics and applications. Their common features include:

Excellent chemical resistance, especially for alkali and acid.  

Strong adhesion to paint film, especially for metal. 

Good heat resistance and electrical insulation. 

Protect the color of paint film well. 

Bisphenol A type epoxy resin coatings feature poor weatherability. Their paint film is easily powdered and lack of fullness, which makes them not suitable for use in outdoor coatings or highly decorative coatings. Thus ordinary epoxy resin coatings are mainly used for anti-corrosion paint, metal primer and insulating paint. However the coatings which are made of heterocyclic or cycloaliphatic epoxy resins can be used outdoors.
